Background
teagood-namakai89 is an npm package that is part of the tea.xyz token reward campaign. This package is designed to facilitate the generation and publication of derivative packages, often with randomized names, to inflate developer reputation scores for token rewards. However, it has been identified as containing malicious code that compromises the integrity of the npm registry.
Vulnerability Detail
The vulnerability in teagood-namakai89 originates from its malicious payload, which modifies the package.json file to remove private flags, alters version numbers, and generates random package names. This behavior leads to the continuous republishing of variants, polluting the npm registry and potentially affecting other packages and developers. The malicious scripts (auto.js, autopublish.js, etc.) are designed to automate this process, making it difficult to track and mitigate the impact.
